IMPROVEMENT m SPRING-BALANCES FOR EXTENSSION-CHANDELIERS.

Specification forming part of Letters Patent N 0. 171,825, dated January4, 1876; application filed July 24, 1875.

To all whom it may concern:

Be it known that I, LYMAN T. LAWTON, of West Meriden, in the county ofNew Haven and State of Connecticut, have invented a new and ImprovedSpring-Balance for Extension-Ohamleliers, of which the following is aspecification:

My invention consists of. a spring-stop in the bottom of the case-of thespring-drum, in combination with notches in'the drum, and having a chainor cord depending from it, all so contrived that the stop will be causedto engage the drum by its spring, to hold it so as to prevent a heavychandelier from falling or a light one from rising, and being so that itcan be readily pulled out of the notches by the cord, to allow ofadjusting the chandelier.

The invention saves the winding apparatus required with the ordinaryspringbalances, and also saves the labor of adjusting the springs fromtime to time to balance the chandelier.

The drawing is a sectional elevation of the case of a spring-balancechandelier, showing the application of my improved stop. Ais the springand chain-drum of a spring-balance, in which are notches B at suitableintervals for receiving the spring-stop C, which is located in the caseD, under the drum so as to slide into and out of said notches, totastenand unfasten the drum from which the chandelier is suspended bychains E, the stop being forced into the notches by'the spring F, andhaving the chain or cord G, suspended from it by which to pull out thestop by hand.

With this contrivance the chandelier may be suspended at any requiredheiglift,' whether the spring is exactly balanced by the weight or not,Whereas in the common arrangement there must be a winding contrivance bywhich to adjust the tension of the spring to the weight, and a ratchetand pawl to hold it when adjusted.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination in a chandelier spring-balance of anotched spring and chain drum A, and a spring-stop, 0, having a pendentcord or chain, substantially as specified.

LYMAN '1. LAWTON.
